Load Circuit for Digital Output Timing Specifications CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the WARNING! AD7450 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to ESD SENSITIVE DEVICE avoid performance degradation or loss of functionality. Rev. A –5–
